Hey when i look at other peoples face rig and real movies, when they move there faceit looks like real life where the skin is trechy to follow the bones, when i move my bones i get some sort of wierd looks.
Also when i for example move the check bone my hair gets twisted and wierdly moved, why?
You mean the “cheek”?
If you move a bone from your character’s face, and the hair is also moved, then there are some vertex of your hair that are being influenced by this bone. To prevent this from happening, you should paint these vertex with influence 0 (see Weight Painting).

CG move with accurate facial movement is done with motion capture:
Doing it with rigging and shape is always a challenge. As ren811 tell you, if a movement is not quite right check weigh painting.
There is a tutorial that Johnathan Ward made using a facial rig that makes it stretchy. Of course, a little weight painting will have to be applied.
